Description
技术领域technical field
本发明涉及显示技术领域，尤其涉及一种柔性基板的背膜贴附方法及装置。The invention relates to the field of display technology, in particular to a method and device for attaching a back film of a flexible substrate.
背景技术Background technique
随着显示技术的发展，越来越多的电子设备中开始使用轻薄且抗冲击特性表现良好的柔性基板。利用柔性基板的显示装置有液晶显示装置、有机电致发光显示装置和电泳显示装置。柔性显示装置可以应用于智能卡、便携式计算机以及电子纸。目前柔性显示的制备工艺有了较大发展，一般是先将柔性基板固定在玻璃基板上，再进行之后的背板制作工艺，这样的工艺与现有液晶显示设备制作工艺相兼容，制备完成后，需要将柔性基板与玻璃基板分离，再在柔性基板的背面贴附膜材(背膜)使柔性基板平整化，之后再进行切割、柔性电路板绑定等工艺。With the development of display technology, more and more electronic devices begin to use flexible substrates that are thin and have good impact resistance. Display devices using flexible substrates include liquid crystal display devices, organic electroluminescent display devices, and electrophoretic display devices. Flexible display devices can be applied to smart cards, portable computers, and electronic paper. At present, the preparation process of flexible display has been greatly developed. Generally, the flexible substrate is fixed on the glass substrate first, and then the backplane production process is carried out. This process is compatible with the existing liquid crystal display equipment production process. After the preparation is completed , it is necessary to separate the flexible substrate from the glass substrate, and then attach a film (back film) to the back of the flexible substrate to flatten the flexible substrate, and then perform cutting, flexible circuit board binding and other processes.
一般地，柔性基板的背膜贴附采用滚轮贴合的方式进行，即通过对置于上方工作台的柔性基板与置于下方工作台的背膜施加滚压作用力使彼此贴合的方式进行贴附。该贴合装置中滚轮外侧为具有弹性的有机材料形成的滚轮包胶，在贴合过程中，由于施加压力的作用，滚轮受到应力而发生形变，导致滚轮包胶两侧形变过大，产生堆积而使得压力过大，而柔性基板和背膜也为有机材料，受力时也会发生形变，因此滚轮包胶两侧形变过大，产生的过大压力导致柔性基板与背膜发生不可逆的形变，从而造成了由于压力差别过大导致的贴合后柔性基板尺寸发生变化，而后续柔性基板与柔性电路板的绑定工艺对基板尺寸变化敏感，因此柔性基板的尺寸的变化会造成绑定时基板上的接线端子与柔性电路板连接的接线端子的错位、电路不通等问题，严重影响了产品良率。对于高世代线，基板尺寸增加，滚轮的尺寸也会增加，上述问题表现更加严重。Generally, the back film of the flexible substrate is attached by roller lamination, that is, the flexible substrate placed on the upper workbench and the back film placed on the lower workbench are applied with a rolling force to make them adhere to each other. attach. In this laminating device, the outer side of the roller is a roller lagging made of elastic organic material. During the laminating process, due to the effect of pressure, the roller is deformed due to stress, resulting in excessive deformation on both sides of the roller lagging, resulting in accumulation The pressure is too large, and the flexible substrate and the back film are also organic materials, which will deform when they are stressed. Therefore, the deformation on both sides of the roller lagging is too large, and the excessive pressure will cause irreversible deformation of the flexible substrate and the back film. , resulting in a change in the size of the flexible substrate after lamination due to an excessive pressure difference, and the subsequent bonding process of the flexible substrate and the flexible circuit board is sensitive to the change in the size of the substrate, so the change in the size of the flexible substrate will cause the bonding time Problems such as the dislocation of the terminals on the substrate and the terminals connected to the flexible circuit board, and circuit failure have seriously affected the product yield. For the high-generation line, the size of the substrate increases, and the size of the roller also increases, and the above problems are more serious.
因此，如何提高柔性基板背膜贴附时的受力均匀性，从而提高柔性基板背膜贴附后基板尺寸的均一性，是本领域技术人员亟待解决的技术问题。Therefore, how to improve the uniformity of force when the back film of the flexible substrate is attached, so as to improve the uniformity of the size of the substrate after the back film of the flexible substrate is attached, is a technical problem to be solved urgently by those skilled in the art.

具体实施方式Detailed ways
下面结合附图，对本发明实施例提供的柔性基板的背膜贴附方法及装置的具体实施方式进行详细的说明。The specific implementation of the method and device for attaching the back film of the flexible substrate provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
本发明实施例提供了一种柔性基板的背膜贴附方法，如图1所示，可以具体包括：An embodiment of the present invention provides a method for attaching a back film of a flexible substrate, as shown in FIG. 1 , which may specifically include:
S101、将柔性基板置于第一工作台面向第二工作台的一面，将背膜置于第二工作台面向第一工作台的一面；S101. Place the flexible substrate on the side of the first workbench facing the second workbench, and place the back film on the side of the second workbench facing the first workbench;
S102、采用滚压机构对置于第一工作台的柔性基板与置于第二工作台的背膜进行滚压贴合；其中，滚压机构的滚轮表面包裹有分段的滚轮包胶。S102 , using a rolling mechanism to roll and bond the flexible substrate placed on the first workbench and the back film placed on the second workbench; wherein, the surface of the rollers of the rolling mechanism is wrapped with segmented roller lagging.
本发明实施例提供的上述柔性基板的背膜贴附方法中，采用滚轮表面包裹有分段滚轮包胶的滚压机构对柔性基板与背膜进行滚压贴合，这样将滚轮包胶进行分段处理可以释放应力，减小滚轮受力时造成滚轮包胶两侧的堆积压力，相对于现有技术中采用滚轮表面包裹单一滚轮包胶的滚压机构对柔性基板和背膜进行滚压贴合，本发明实施例采用滚轮表面包裹分段滚轮包胶的滚压机构对柔性基板和被膜进行滚压贴合，这样可以分散压力防止单一滚轮包胶两侧产生过大的形变压力，从而对柔性基板与背膜进行滚压贴合时可以提高柔性基板的受力均匀性，进而提高贴膜后柔性基板尺寸的均一性。In the method for attaching the back film of the above-mentioned flexible substrate provided by the embodiment of the present invention, the rolling mechanism with segmented roller lagging wrapped on the surface of the roller is used to roll and bond the flexible substrate and the back film, so that the roller lagging is divided Segment treatment can release the stress and reduce the accumulation pressure on both sides of the roller lagging caused by the force on the roller. Compared with the prior art, the rolling mechanism that uses the roller surface to wrap a single roller lagging is used to roll the flexible substrate and the back film. Combined, the embodiment of the present invention uses a rolling mechanism that wraps the surface of the roller in sections and covers the flexible substrate and the film by rolling and laminating, so that the pressure can be dispersed to prevent excessive deformation pressure on both sides of the single roller covering, thereby When the flexible substrate and the back film are rolled and laminated, the force uniformity of the flexible substrate can be improved, thereby improving the uniformity of the size of the flexible substrate after the film is pasted.
在具体实施时，可以将第一工作台设置为上方工作台，将第二工作台设置为下方工作台，也可以将第二工作台设置为上方工作台，将第一工作台设置为下方工作台，在此不作限定，具体地，下面以第一工作台为上方工作台，第二工作台为下方工作台为例进行说明。In specific implementation, the first workbench can be set as the upper workbench, the second workbench can be set as the lower workbench, or the second workbench can be set as the upper workbench, and the first workbench can be set as the lower workbench The table is not limited here. Specifically, the following description will be made by taking the first workbench as the upper workbench and the second workbench as the lower workbench as an example.
在具体实施时，本发明实施例提供的上述方法中，还可以包括：在滚轮上相邻两段滚轮包胶之间设置切割刀轮，对置于上方工作台的柔性基板与置于下方工作台的背膜进行滚压切割。具体地，由于背膜和柔性基板也为有机材料，受力时也会发生形变导致应力累积，因此，为了减小柔性基板在背膜贴附时的形变，可以在滚轮上相邻两段滚轮包胶之间增加切割刀轮，在进行滚轮压合时，切割刀轮首先接触背膜和柔性基板，将其切割成条状膜材，随压力增加，滚轮贴合至背膜进行压合，这样可以防止了大片背膜和柔性基板受力时挤压形变的问题。In specific implementation, in the above-mentioned method provided by the embodiment of the present invention, it may also include: setting a cutting knife wheel between two adjacent sections of roller lagging on the roller, facing the flexible substrate on the upper workbench and placing it on the lower workbench. The back film of the table is rolled and cut. Specifically, since the back film and the flexible substrate are also organic materials, deformation will also occur when the force is applied, resulting in stress accumulation. Therefore, in order to reduce the deformation of the flexible substrate when the back film is attached, two adjacent rollers can be placed on the roller A cutter wheel is added between the lagging. When the roller is pressed, the cutter wheel first contacts the back film and the flexible substrate, and cuts it into a strip of film material. As the pressure increases, the roller is attached to the back film for pressing. In this way, the problem of extrusion deformation when the large back film and the flexible substrate are stressed can be prevented.
